The CHEM Model

The CHEM model has profiles made of double anodized aluminum. The articulating arm is ideal for fume extraction in aggressive environments where corrosion resistance must be assured. The extraction arm shown here is fitted with a painted, corrosion-resistant metal hood.

The new generation of Nederman BenchTop arms is available in 2, 3 and 4 in. (50, 75 and 100 mm) versions with corresponding capacity ranges of:
FX75-     3": 65-140 cfm (110-240m3/h)
FX100-  4": 120-265 cfm (200-450 m3/h)

Exhaust Snorkel Hoods

Combi Hood

Are designed to exhaust contaminants with low energy. The transparent combi hood is made of PET-G plastic.

It can be attached directly to the lab exhaust snorkels regardless of the size of the arm.

Handles on both sides of the hood make it maneuver easier.

Dome Hood

Transparent dome hood is designed to be used with high dispersion contaminants. The transparent hood is made of PET-G plastic.

It can be attached to the hood regardless of the size of the extraction arm.

Handles on both sides of the hood make it maneuver easier.

Metal Hood

The powder-coated white metal hood is made of aluminum and is designed to capture contaminants. It is capable to handle aggressive fumes, high temperatures, and corrosion resistance, and dust splatter.

It can be attached to the exhaust hood of any size articulating arm.

Drop Ceilings Installation

You need to add the “43+ inch additional tube extension” which can be cut down to size to go thru the drop ceiling. You can also add the "ceiling cover plate" that will conceal the hole, but it is not required; it is only for aesthetic purposes.
